Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

Woese and Fox's 1977 paper on the discovery of the Archaea triggered a revolution in the
field of evolutionary biology by showing that life was divided into not only prokaryotes and …

Glycerol dialkyl glycerol tetraether (GDGT) lipids are membrane lipids which were long
thought to be synthesized mainly by archaea, organisms thought to be limited to extreme …

Genes of archaea encoding homologues of ammonia monooxygenases have been found
on a widespread basis and in large amounts in almost all terrestrial and marine …

Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in
the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing …

The discovery of complete ammonia oxidizers (comammox) refutes the century-old
paradigm that nitrification requires the activity of two types of microbes. Determining the …

Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested to
have been a central part of the global biogeochemical nitrogen cycle since the oxygenation …

Ammonia oxidation is a fundamental core process in the global biogeochemical nitrogen
cycle. Oxidation of ammonia (NH3) to nitrite (NO2−) is the first and rate-limiting step in …

The discovery of ammonia-oxidizing archaea (AOA), now generally recognized to exert
primary control over ammonia oxidation in terrestrial, marine, and geothermal habitats …

Thaumarchaeota range among the most abundant archaea on Earth. Initially classified as
'mesophilic Crenarchaeota', comparative genomics has recently revealed that they form a …
